WILDMAN, OF SYTDI TEZ, AUSTRALIA.

SANITARY CLOSET.

Application filed September 1, 1923.

T all whom it may concern:

Be it known that I, JAMES VVILDMAN, a subject of the King of Great Britain, residing at Sydney, in the State of New South Wales, Commonwealth of Australia, have invented certain new and useful Improvements in Sanitary Closets, of which the following is a specification.

This invention relates to that class of 1 sanitary closet in which the faecal matter and other soluble contents are acted upon by a chemical solution. The object of the invention is to provide reliable means whereby the feecal matter and paper will be carried into the chemical solution tank without splashing, and completely removed from the means of conveying it.

According to the invention, I provide in the solution tank an endless chain or flexible perforated conveyor rotatable over two or more rollers, preferably three, in such a manner that immediately below the pan opening into the conveyor is in an approx mately horizontal position. Movement of the conveyor is effected preferably by means of a rod or rods actuated on raising or lowering the seat or seat cover, or by a foot or hand lever, whereby pawl and ratchet or other gearing causes sprocket or other wheels to move the conveyor a short distance at a time sufliciently to carry the fzecal matter and paper into the solution. In contact with the conveyor, either in its downward or upward travel, or both, there may be one or more scrapers adapted to break up and remove any matter or paper which may adhere to it. v r

The solution preferably reaches to within an inch or two below the horizontal portion of the conveyor.

But in order that my invention may be more clearly understood I will now refer to the accompanying drawings in which is illustrated a closet constructed according to the invention.

Figure 1 is a sectional side elevation, and

view of the ratchet wheel and pawls, and

Figure 7, a cross section on line 7-7, Figure 6.

Figure 8 is a part perspective view of the driving wheel teeth meshing with the conveyor links.

The same numerals indicate the same or corresponding parts throughout the drawings.

10 is the pan of the closet with the liquid chemical containing tank 11 positioned on the underside thereof. 12 is the seat and 13 the seat cover, said cover 13 having the connecting rods 14: and 15 pivoted thereto at 16. The opposite ends of these rods 14 and 15 are connected to arms 17 and 17 respectively. 18 and 19 are pawls pivoted at 20 and 21 to the arms 17 and 17 said pawls engaging the ratchet wheel 22 mounted on the squared shaft 23. On this shaft 23 is also mounted two or more gear wheels 24, the teeth 25 of which are adapted to mesh with the conveyor links 26. This conveyor comprises a number of these links 26, the ends 27 of which hook over the neXt adjoining link to form an endless conveyor.

Rollers 28, 29, and 30 are positioned in the liquid tank 11 over and through which the conveyor is adapted to pass. The shaft 31 of the roller 29 is extended and provided with small agitators 32 to stir up and circulate the liquid. A stop cock 34 or other suitable valve with handle 3 1 may be fitted to the tank 11 to empty same. 35 is the overflow with guard 36,-so that only liquid from under the level in the tank may flow therethrough. 33 is a bridge shaped portion of the rear of the pan 10 to allow paper or other matter to pass thereunder.

In operation, on raising the seat cover 13, or both the seat 12 and cover 13, the rods 14: and 15 are forced downwardly, the pawl 18 turning the ratchetwheel 22, and the other pawl 19 overriding the teeth. The gear wheels 24 are correspondingly turned and move the conveyor links 26 towards the rear of the closet, allowing a fresh portion of the conveyor to move across the pan opening. When it is desired to close the closet, the cover 13 is lowered moving at the same time the rods 14. and 15, the pawl 19 turning the ratchet wheel 22, and the pawl 18 riding over the teeth, causing the conveyor to move a further distance.

The liquid and semi-liquid matter which fall onto the conveyor pass directly through the conveyor being moved, the more solid matter and paper are carried down into the chemical solution by which they are d1ssolved.

I do not restrict myself to any particular solution, but I find that a strong caustic solution very suitable for the purpose.

Having thus described my invention, What I claim as new and desire to protect by Letters Patent is 1. In sanitary closets in which faecal matter and other soluble contents are acted upon by a chemical solution, the combination With a closet pan, of a tank or chamber positioned below and in communication with said pan, an endless chain or flexible conveyor movable across the opening between the pan and adapted to be passed through a chemical solution within the tank, and means for actuating the conveyor.

2. In sanitary closets as claimed in claim 1, means for actuating the conveyor,

consisting of a rod pivoted to the closet seat element, adapted to actuate through a pawl, a gear wheel in engagement with the conveyor on raising or lowering said seat element.

In testimony whereof I have hereunto set my hand.
